We're not too far away; located in Santa Clara next to San Jose!

Passing Emissions
Martin- What are your cam specs? That will determine it for you. We have 2 cams that we have been testing that seem to pass the sniffer test. We try to make all of our packages emissions friendly. If you want to e-mail me your specs, I can give you an idea. Thanks! -Wayne- LTHL VPR

Has anbody else smelled their clutch burning?
I agree with most of the comments above. It's not a good idea to ride the clutch. The Viper clutch is OK, but we have found great success upgrading the clutch to use dual kevlar clutch discs! We have been using the same style on our customer's Race Mustangs for years and some of these cars have...- LTHL VPR

who can remap the ECU?
When you say 'remap', I take it to mean that you have full control over all the major PCM parameters. To the best of my knowledge there are only 1-2 programs available for 'tuning' the Viper. Neither of them are that great, and ONLY allow for controlling some of the parameters. Nothing close to...- LTHL VPR

X pipe section in rear section of 99 GTS exhaust
Through our R&D efforts, we tried using a 3" X pipe in the rear near the differential. The headers and mufflers play the major role in the final sound of a system. The X-pipe certainly made the sound more tame, not as much burble and loping; it seemed to smooth out the pulses and flow coming...- LTHL VPR

Yellowing sills and cats
I know of a few people who have used the VHT1500-2000 and the sill still discolored. It does seem to cut down on the heat, but it may just prolong the process. We have also used a high heat cloth, in addition, to the side sill insulation. Together, this cuts down on the temperature noticeably...- LTHL VPR

What do you track rats do for not so "cool"ant temps??
Re: What do you track rats do for not so \"cool\"ant temps?? Dion- I noticed the you have an early GENII (judging by paint scheme). Have you upgraded your fan yet? In late 98, the fan unit was upgraded to provide an increased pull through the radiator. If you don't have the upgrade yet, it's a...- LTHL VPR

Need input on stereo design
Have this shop installed a system in the Viper before? With MB Quart 6.5" in he doors they will have to trim the plastic and metal slightly for them to fit flush, allow the grills to fit, and to close the door properly.

Best brand/price on 1.7 roller rockers??

((((((((((Subwoofer installation))))))))))))
As you probably know, it really depends on what you want to do with the trunk. Use all space, some space, remove the spare, etc.. As for Subs, it tough to beat the Kicker square Solobarics. When I install systems in my cars, I try to avoid any drilling, cutting, and I like to keep the spare. I...- LTHL VPR

how to install B&M short shifter (ripper shifter)
We recommend that you drop the tranny when you install it; that's what we do. It eliminates any drilling in the tranny tunnel getting through those TOUGH stainless rivets. No better time to upgrade the Flywheel and Clutch! We have both in stock. Call me if you have any questions or trouble with...- LTHL VPR
